We are introducing our first OWA2010 in the head office this month. Question: We have an Exchange 2007 SP3 Server with all roles on it running in a remote site. Lets say a user-A resides on this server. Now when s/he accesses the link https://webmail.domain.com/owa from the internet, how will his/her request proxy to his/her MBX Server. I have read documents online on how this works, just wandering what settings would I have to configure on my first OWA2012 and/or on Exchange 2007SP3 in the remote site to route such requests to their mailboxes, flawlessly? Advise Please. Thank you
